Abstract

Chaos communication system is possible to improve the system security by using chaos signal. Further, it is possible to reduce the possibility of eavesdropping, and has strong characteristics from interference signal and jamming signal. However, BER performance of chaos system is worse than digital communication system. By this reason, researches for BER performance improvement are being studied actively. In previous studies, we proposed a novel chaos map for BER performance improvement, and called it `Boss map'. Also, we proposed a novel chaos transceiver for BER performance improvement. However, BER performance is evaluated differently according to delay time of chaos transceiver. Therefore, for effective using of Boss map, we should find the optimal delay time in CDSK system and proposed chaos transceiver. In this paper, when Boss map is used, we evaluate BER performance of CDSK system and proposed chaos transceiver according to delay time. Also, we find a delay time that is possible to have best BER performance in CDSK system and novel chaos transceiver after evaluation of BER performance according to delay time.

分析CDSK系统中基于延迟时间的boss图，提出混沌系统

混沌通信系统可以利用混沌信号来提高系统的安全性。进一步，可以降低被窃听的可能性，并且具有较强的抗干扰信号和干扰信号特性。然而，混沌系统的误码率性能比数字通信系统差。因此，提高误码率性能的研究正在积极进行。在以往的研究中，我们提出了一种新的混沌映射来提高误码率，并将其称为“Boss映射”。此外，为了提高误码率，我们还提出了一种新的混沌收发器。然而，混沌收发器的误码率性能根据时延的不同而有不同的评价。因此，为了有效地利用Boss映射，我们需要在CDSK系统中找到最优延迟时间，并提出混沌收发器。在使用Boss映射时，我们评估了CDSK系统的误码率性能，并根据延迟时间提出了混沌收发器。此外，我们还根据延迟时间对CDSK系统和新型混沌收发器的误码率性能进行了评估，并找到了可能具有最佳误码率性能的延迟时间。
